The Giants are a baseball team located in Daten City. Based on the Yomiuri Giants. In "Heroine Interview", the team was seen celebrating a victory. Shortly after, a member of The Giants named Mara, a play on the name of the manager, Tatsunori Hana, sent an invitation to Panty, asking her to throw the ceremonial first pitch of the next season.
A few months later, Panty attended the game, but instead of throwing the first pitch, she shoved the baseball in her uterus.
